WASHINGTON — The Senate is poised to pass Donald Trump’s request to cancel about $9 billion in foreign aid and public broadcasting spending, moving forward on one of the president’s top priorities despite concerns from several Republican senators.

The legislation, which would go next to the House, would have a tiny impact on the nation’s rising debt but could have major ramifications for the spending that is targeted, from the Corporation for Public Broadcasting to U.S. food aid programs abroad. It could also complicate efforts to pass additional spending bills this year, as Democrats and some Republicans have argued that they are ceding congressional spending powers to Trump with little idea of how the White House Office of Management and Budget would apply the cuts.

The move to claw back a sliver of federal spending comes after Republicans also muscled Trump’s big tax and spending cut bill to approval without any Democratic support. The Congressional Budget Office has projected that measure will increase future federal deficits by about $3.3 trillion over the coming decade.

Senate Majority Leader John Thune, R-S.D., said Republicans were using the president’s rescissions request to target wasteful spending, and it is a “small but important step for fiscal sanity that we all should be able to agree is long overdue.”

Senate Appropriations Committee Chairwoman Susan Collins, R-Maine, said the bill “has a big problem — nobody really knows what program reductions are in it.”

Collins was one of three Republicans who voted against moving forward with the bill in a Tuesday procedural vote, along with Sens. Mitch McConnell of Kentucky and Lisa Murkowski of Alaska. Vice President J.D. Vance cast a tiebreaking vote to pass it.

Collins and Murkowski both expressed concerns about the cuts to public broadcasting, saying they could affect important rural stations in their states. Murkowski said in a speech on the Senate floor Tuesday that the stations are “not just your news — it is your tsunami alert, it is your landslide alert, it is your volcano alert.”

Less than a day later, as the Senate debated the bill, a 7.3 magnitude earthquake struck off the remote Alaska Peninsula, triggering tsunami warnings on local public broadcasting stations that advised people to get to higher ground.

The legislation would claw back nearly $1.1 billion from the Corporation for Public Broadcasting, which represents the full amount it’s due to receive during the next two budget years. The corporation distributes more than 70% of the money to more than 1,500 locally operated public television and radio stations, with much of the remainder assigned to National Public Radio and the Public Broadcasting Service to support national programming.

The legislation would also claw back about $8 billion in foreign aid spending. Among the cuts are $800 million for a program that provides emergency shelter, water and sanitation and family reunification for those who flee their own countries and $496 million to provide food, water and health care for countries hit by natural disasters and conflicts. There’s also a $4.15 billion cut for programs that aim to boost economies and democratic institutions in developing nations.
